Want to make a unique BL truggy. Need Ideas.

First off I want to say that, whatever I end up doing, I want a 3 speed transmission in it. Which basically means i will be using a Savage 3sp trans.

I'm going to start a new on this one, as of now i've got nothing in terms of equipment. However I do have ideas. But i'll start w/ questions (assume cost is no factor):

What truggy should I get? I've been in the Maxx world for all my time, and now I think it is time to get informed on truggies. What I am looking for is a truck that will somehow accomodate a 3sp trans, two 5S3P lipo packs in series making a 37 volt 12000mah powersource, 40160 esc, and large (undecided) lehner motor. This truggy needs to be BIG, DURABLE, good handler, w/ a flat and "BL conversion friendly" chassis.

Which Lehner should i purchase rated for 37 volts?

I've also been seeing a lot of talk about heatsinks. Anyone know about water-cooled systems? I would definatley need some sort of heat system for my 40160, and maybe even my batteries.

Thanks guys
